"It's going to be difficult. It's going to be hard," Biden said. "The House has already passed a really good bill.

"I
used to joke when I was a senator, and some of you who covered the
Senate remember these kind of phrases. I used to say, you know, 'say
it's going to happen; this is going to pass,'" Biden said. "'Well, how
do you know?' And I say, 'I don't know, but I'll tell you when the
horses smell the water.'"

Biden said there is a "clear consensus" on Capitol Hill that
"they've got to do something to deal with the amount of carbon that we
emit into the air and the amount of oil we consume from abroad."
